An electrooxidation process, which involves electrolysis of ore- brine slurry, was shown to result in favorable metal extraction from gold, silver, antimony, mercury, and molybdenum source materials.

Hydrometallurgical Processing ScienceDirect

2014-1-1  Gold Processing2.7.3.1. Gold Extraction. Gold is a noble metal because of its ability to retain its electrons in very oxidizing environments. The ability of an atom to retain electrons is measured by its electrochemical potential. Gold has a standard electrochemical reduction potential above 1.4 V from its auric or aurous state. Common

Selection on the Process for Removing and

2017-2-7  And then pressure oxidation technology was applied to prepare sodium pyroantimonate from sodium thioantimonite solutions. This process is more promising owing to its high removal ratio of antimony, low production cost and environment friendly, which provides a positive guidance for the extraction of antimony from antimonial refractory gold ores.

Froth Flotation and Gold Extraction Manhattan Gold

2014-7-23  Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
